Alex O’Loughlin will be missing at least one episode of Hawaii Five-0 while he completes treatment for prescription drugs.

The 35-year-old actor “is taking a short break to receive supervised treatment for prescription pain medication due to a recent shoulder injury,” his rep said in a statement (via EW).

“We respect and support Alex’s decision,” CBS Studios, which produces the drama, added. “Everyone at CBS TV Studios and Hawaii Five-0 wishes him well and we look forward to his return.”

Alex‘s treatment is not expected to affect production, which has already filmed 19 episodes. After episode 20 is completed, the show will then take a short break before filming three more episodes for its second season.

The 37-year-old Great Gatsby actor “has embraced the spirit of the Australian man of today. At GQ we like a man with patience, skill and the determination to take the ups and downs of life, but never give up on his dream, and this is the reason why we have named Joel our Man of the Year,” editor Nicholas Smith said.

Hawaii Five-0 star Alex O’Loughlin, who was named the mag’s Actor of the Year, and Charlie’s Angels‘ Rachael Taylor (Woman of the Year) also got their own covers!

Alex “caught the acting bug when he performed in a play at primary school, aged 10, but never in his wildest dreams thought it was something he could do for a living. No – that kind of work was for the bourgeoisie – not someone from a working-class suburb in Canberra. Instead, he left school young, built houses, made cocktails, waited tables – not realising that the little seed was still in there, and had taken root. Since then, his drive, passion and hard work have turned him into one of our hottest acting exports of all time,” GQ Australia notes.

Alex O’Loughlin wraps his arm around his son Saxon on the set of Hawaii Five-0 on Sunday (July 31) in Oahu, Hawaii.

The 34-year-old actor enjoyed some downtime with Saxon, who lives with his mom in Australia, and co-star Scott Caan.

Alex‘s character on the hit CBS show may be getting a new love interest for the upcoming season.

Happy Town actress Lauren German is joining the cast to play a “smart and beautiful former Homeland Security officer who has been hand-picked by the new governor to join the Five-0 task force,” TV Line reports.
